The Claim
Both InVEST training and the National Institute on Aging's strength training program produce equivalent improvements in muscle strength among mobility-limited older adults, with approximately 19–20% increases in one-repetition maximum (1RM) after 16 weeks of supervised training.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After 16 weeks of supervised strength training, both the InVEST program and the National Institute on Aging's program result in a 19–20% increase in one-repetition maximum strength in older adults with limited mobility.

When older adults lift weights, their nerves send stronger and faster signals to their muscles, causing more muscle fibers to turn on at once. This lets the muscles generate more force, which makes them stronger over time.
What the research says
1 studyBoth exercise programs helped older adults with mobility issues get stronger by about the same amount—roughly 20%—so it doesn’t matter which one they did if the goal is just to build muscle strength.
